Researchers from the Chemistry Department of the US Naval Research Laboratory (NRL) have developed a new type of battery - rechargeable zinc batteries, which they claim are safer than lithium batteries. And its research institute has been banned on naval vessels and other special platforms due to the flammability of lithium-ion batteries.

This study suggests that rechargeable zinc batteries have similar capacity to lithium-ion batteries, but are lower in cost, faster in speed, smaller in size, and lighter in weight. They are expected to be applied to hybrid energy vehicles, electric vehicles, electric bicycles, and even mobile phones and large-scale energy storage devices. Is the era of lithium-ion batteries really coming to an end? Let's first learn about this new type of zinc battery.

Mitchell, CEO of EnZinc, a battery technology company based in San Anselmo, California? Michael Burz stated that they are preparing to test and promote this technology, hoping to achieve good results.

Debra? Debra Rolison, the head of the Advanced Electrochemical Materials Division at the US Naval Research Laboratory in Washington, D.C., was also involved in the research of this zinc battery. He believes that the biggest weakness of lithium batteries is their tendency to overheat and even catch fire and explode. The US Navy has been looking for a technology to replace lithium batteries to avoid the potential harm of lithium battery instability to military personnel and weapons. The fire hazard of zinc batteries is much lower than that of lithium batteries, and the energy storage per unit volume and per unit mass is not lower than that of lithium batteries. In addition, zinc has more reserves on Earth than lithium and is much cheaper. Therefore, zinc batteries are a promising next-generation rechargeable battery.

However, for a long time, zinc batteries have been considered non rechargeable because after only a few rounds of charging, conductive filaments are generated between the two electrodes inside the zinc battery, ultimately leading to a short circuit between the two electrodes. And this time, the US Navy research team has found a way to suppress the generation of electric filaments inside batteries by making the zinc anode into a porous sponge like structure. In this way, during the charging and discharging period of the battery, the current distribution on the zinc anode will be more uniform, making it difficult to generate conductive filaments.
